BRAKE AND HAULING DEVICE FOR AUTOMOBLES.

Application filed. May 22, 1924. Serial No. 715,181.

[o ZZ whom t may concern.:

"Be it known that I, JOHN Knnrrzns, a citizen of Can-ada, residing atPlunkett, in the Province of Saskatchewan and Dominion of Canada, haveinvented certain new and useful improvements in Brake and HaulingDevices for Automobiles, of which the following is a specification.

This invention relates to new and useful improvements in brake andhauling devices for automobiles.

An important object of the invention `is to provide apparatus which maybe used in connection with automobiles for the pur'- pose of braking thespeed of travel of the same, locking the vehicle to prevent movement ineither direction by an unauthorized person, and hauling the machine outof a mud-hole or the like by. its own power.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like `parts throughout thesame,

Figure 1 illustrates a partly bottom plan automobile dash board showingthe points of control of the apparatus illustrated in Figs. 1, 2, 3 and4,

Figure 6 is a fragmentary vertical sectionalv view of the dash board andthe apparatus controls associated therewith,

'.Figure 7 is a fragmentary vertical sectional view of part of thecontrols illustrated in Fig. 6 and further shows an operating elementconnected thereto.

Figure 8 is a detail elevational view of a portion of the controllingelements illustrated in Figs. 6 and 7 Figure 9 is a fragmentaryelevational view of a cable conduit illustrated in Figs. 1 and 2, andFigure 10 illustrates a detail elevational view of the operating'elementi shown in action in Fig. 7.

1n the drawings, wherein for the purpose of illustration is shown apreferred embodiment of this invention, the numeral 5 illustrates thedifferential housing associated i with the rear axle 6 and the rearaxle. housing 7. Suitably formed with this diiferential housing and therear axle housing 7 is a casing 8 which is of cylindrical form andencloses the axle 6.

Formed integrally with the casing 8 and extending longitudinally ofthe'automob-ile is a tapered conduit 9 having a coupler 10 threadedlyconnected vto its forward end. This coupler 1G is constructed to connectto the outer end of the tapered conduit 9 a section of tubing 11 whichis of greater diameter than the forward, reduced end of the taperedconduit 9, thereby forming a shoulder 12. rlfhis tubing 11Vis connectedto the front axle 13 by a pair otU-bolts 14, as best illustrated inFigs. 1 and 2. Loosely mounted upon the rear axle 6 is a drum 15 whichis provided at one end with a series of lugs 16 that are intended to beused as a portion of a clutch structure. The drum 15 is provided at itsopposite end with a hub portion 17 having a reduced projection 18extending concentrically therefrom. A cable 19, formed of non-elasticmaterial, is intended to be wound upon the drum 15, with its inner endsecured to said drum, and extends longitudinally through the taperedconduit 9 for ,the purpose of having secured to its outer end a spike20. Encircling the cable 19 is a spring 21 that bears at its outer endagainst the head of the spike 20 and at its inner end against theshoulder 12. It will be seen that this spring 21 normally retains thepoint of the spike 20 projecting from the end of the tubing 11. Y

Rigidly secured to the rear axle 6 is a sleeve 22 which carries aratchet wheel 22?l and has projecting from one side thereof a series oflugs 24 which are intended to cooperate with the lugs 16 carried by thedrum 15 for forming a complete clutch structure. Extending forwardlyfrom the casing `8` and communicating therewith is an L-shaped conduit25 which has its upper end terminating in proximity to the dashboard260i' the 2S is provided with a bore 29 within which a. stub shaft 30 iskeyed or otherwise secured for preventing rotation. This shaftisprovided lwith an enlarged, squared portion 31 which is positioned inproximity tothe outer face of the boss 28. rl`he enlarged end 32 ofVthis shaft 30 is received within a cup-shaped bracket 33 which issecured Vwithin a relatively large opening 34 formed in the dash boardby means of a 35 which is secured to the said dash board. Slidablymounted upon the shaft 30 is a grooved wheel 36 which is provided with asquared bore 87 adapted for snugly` fitting the 'squared portion 31 ofthe shatt and 'tor loosely engaging the remaining portion olf thelatter. Encircling the shalt 30 Vand bearing against the grooved wheel36 and theV inner end of the cup-shaped bracket 233 is a compressionspring V38 which' normally operates for retaining the wheel upon thesquare portion 31 of the lshalt B0, thereby preventing rotationl of thewheel. Secured to the periphery of 'the grooved wheel 36, as at 40, is acable 39l which extends through the borejof the conduit 25 and issecured at its c rear'end to a pawl 41 which is pivotally lCil mounted,as at 42 within the casing-8 and is loca-ted in operative relation withthe ratchet A spring 43 is associated with this pawl 41v andA operatesfor normally' retaining` the latter out of engagement with the ratchet23. 'A second conduit 44 communicates with the casing '8 at its rear endand extends lorf ward-ly and vupwardly to terminate in proximity to theend of the conduit 25.Y A cable l5-extends through this conduit 44 andis connected tothe grooved wheel 36, as at 40. This cable 45v isconnected at its rear end to a pivotal cam 46 which is mounted inproximity to the enlarged hub 17 and concentric projection 18 of thedrum 15. f lAn-arm 47 is lformed integrally with the U-shaped bracket 27secured to the dash board-26and 'is employed for rotatably supportingaxsheave 48 upon which a relatively short cable 49 Lis arranged. Thiscable is in- `tended to'be connected at its outer end to the cable 45andl at its inner end to the' shank 50 Aoi a plu-g which is providedwith a flange "51,l adapted for lushly engaging: the front face of thedash board 26 when not in operathe tubing 11 should be removed forpermitting the elbow 54 to be attached thereto. This elbow has its outerwall cutaway, as at 55 for permitting the spike 20 to pass around thebend of the said elbow. In Fig. 2, the spike 20, with its-cable 19 havebeen illustrated as withdrauni from the tubing 11 and conduit 9 and thespike 2O has been driven into the ground G rearwardly of the iront axle13. lt is to be understood that the cable 19, as illustrated in Fig. 2,has been entirely unwound from the drum 15. The operator should then.connect his engine with the rear axle ti in such a manner that thelatter will operate for driving the vehicle to the rear. 'lhe plughaving the operating ring 52 should then be pulled outwardly oi* thedash board 2G, by this ring, `tor drawing upon the cable 45. Thismovement oi the cable 45 will pivot the cam 46 -For causing the same toengage the hub 1i' and projection 18 of the drum 15 for moving the lugs16 into engagement with the cooperating lugs 24. lt will now be seenthat the drum has been locked to the shaft G and that rotation of thelatter will wind the cable 19 upon the drum for moving` the vehiclerearwardly, thereby removing` the rear wheels from the mud-hole. lt isto be understood that the elbow 54 may be dispensed with and the cable19 with the spike 2() extended Jforwardly oi' the liront axle 18. .Vhenthe spille 2() is in front oi' the vehicle, the rear axle should bedriven for moving the automobile forwardly thereupon winding the cable19 upon the drum 15 ior moving the rear wheels out of the mud-hole.

During the travel of the vehicle over a highway, the driver may withdrawthe plug 51 from the dashboard for drawing upon the cable 45 to causethe drum 15 to be shifted toward the pawl 23 for intermeshing the lugs16 and 24 to lock Athe drum upon the rear axle G. Further movement ofthe rear axle will cause the cable 19 to be wound upon the drum formoving the spike 2O longitudinally inwardly through the tubing 11thereby compressing the spring 21. VThe spike 20 will be permitted tomove tlnough the tubing 11 until its head engages the completelycompressed spring 21-which is prevented from moving bodily by theshoulder 12. The spikewi-ll then be held against further movement andthe rear axle will be locked.

'Vhen the` operator ol the automobile desii-es to leave his vehicleparked, he may employ the element illustrated in Figs. 7 and 10. Thiselement comprises a stein carrying a knob 5T at one end and a pair otspaced arms 58 at the other end. The outer end oi each ot these arms 5Sis provided with ay cross arm 59 which projects laterally from each sideoi the said arm 58. The inner Ytace et the grooved wheel 36 is provided"to be wound upon the said `vheel.

with a pair otarcuate recesses having lateral projections 6l which donot open outwardly through the tace oft the wheel 36.

grooved wheel By slightly rotating this operating` element, the crossarms 59-will be received within diametricallv opposed extensions 61 andthe wheel may then' be moved longitudinally ot the shaft 50 tordisengaging the squared bore oit the wheel troni the squared `portion 3lot the shaft. rlhis wheel may then bev rotated counterclockivise. torcausing the cables 39 and 45 rlhis moven'ient ot' thecables 39 and i5will cause the pawl di, to be'moved into operative relation with theratchet 23 and the cam 4,6 to be moved into engagement with the hub 1Tand the projection 18 tor moving thev clutch lugsl into engagement withthe lugs Q4. jitter the pawl 4:1 and cam t6 have been l moved intothesepositions, the wheel may be allowed to move back upon the squaredportion 3l ot the shatttor preventing rotation otthe said wheel'.` Itwill now be seen thatV the-drum 15 will be prevented trom rotating treeot the axle 6 and that the pawl `rtl will prevent rotation ot this axlein one direction. lIt will now be seen that should a person, not owningthe automobile equipped with this apparatus, endeavor to move thevehicleforwardly, the drum 15 would wind the cable upon itself 'formoving the head ot the spike 20 inwardly tor compressing the spring 2l.After this spring has been fully compressed, further movement ot thevehicle to the `front would be prevented. The unauthorized personattempting to drive the vehicle would be prevented itrom moving the sameto the rear by the pawl 4l.. 1t, therefore, will be seen that this.device may be employed tor locking the auto-mobile to prevent anunauthorized person 'from stealing the same.

1t is now believed that the construction ot the various elements and themanner of assembling the same will be understood trom the above detaildescription, also that the various ways ot' employing this apparatushave been cle-arly disclosed so that any vehicle driver couldsuccessfully use the same.

It is to be understood that the form of this invention herewith shownand described isto be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement ot parts may beresorted to without departing trom the spirit of the invention or thescope ot the subjoined claims.
